“…Estimates for wear-corrected overeruption thus range from 0.50 to 1.3mm. Using modern human population data on overeruption as a reference (Craddock and Youngson 2004;Craddock et al 2007), this indicates a loss of the mandibular RP4 minimum several months to several years before death (Fig. 11B).…”

Objectives: Due to the scarcity of the fossil record, in-vivo changes in the dentognathic system of early Homo are typically documented at the level of individual fossil specimens, and it remains difficult to draw population-level inferences about dietary habits, diet-related activities and lifestyle from individual patterns of dentognathic alterations. The Plio-Pleistocene hominin sample from Dmanisi (Georgia), dated to 1.77 million years ago, offers a unique opportunity to study in-vivo changes in the dentognathic system of individuals belonging to a single paleodeme of early Homo. Materials and Methods: We analyze dentognathic pathologies in the Dmanisi sample, and in comparative samples of modern Australian and Greenlander hunter-gatherer populations, applying clinical protocols of dentognathic diagnostics. Results: The Dmanisi hominins exhibit a similarly wide diversity and similar incidence of dentognathic pathologies as the modern human hunter-gatherer population samples investigated here. Dmanisi differs from the modern population samples in several respects: At young age tooth wear is already advanced, and pathologies are more prevalent. At old age, hypercementosis is substantial. Discussion: Results indicate that dentognathic pathologies and disease trajectories are largely similar in early Homo and modern humans, but that the disease load was higher in early Homo, probably as an effect of higher overall stress on the dentognathic system. Key words: aging, tooth wear, caries, periodontitisThe Plio-Pleistocene site of Dmanisi has yielded a large sample of hominin fossils associated with abundant and diverse faunal remains and Mode I stone artifacts (Gabunia et al. 2001;Ferring et al. 2011;Mgeladze et al. 2011). Occupation of the site began shortly after 1.85 Ma. The fossil hominin finds are dated to 1.77 Ma (Ferring et al. 2011). Dmanisi thus represents the earliest evidence of Homo outside of Africa. The well-preserved cranial, mandibular and postcranial remains of five individuals are unique in offering detailed insights into patterns of morphological variation within a paleodeme of early Homo, and into patterns of growth and aging Margvelashvili et al. 2013;Zollikofer et al. 2014). The craniomandibular morphology of the Dmanisi paleodeme has been described previously (Gabunia and Vekua 1995;Gabunia et al. 2000;Gabunia et al. 2001;Gabounia et al. 2002;Lordkipanidze et al. 2005;Lordkipanidze et al. 2006;Rightmire et al. 2006;Rightmire and Lordkipanidze 2010;Lordkipanidze et al. 2013;Margvelashvili et al. 2013). Cranial and mandibular morphological variation within the Dmanisi paleodeme is wide, but well within the range of variation seen in modern humans populations, and in populations of chimpanzee subspecies (Skinner et al. 2006;Lordkipanidze et al. 2013;Margvelashvili et al. 2013;Zollikofer et al. 2014). Variation in size, shape and dentognathic features among the Dmanisi mandibles has received special attention and has been studied to address questions of phylogeny, taxonomy, sexual dimorphism, die...

“…5 Similarly, orthodontic extraction of upper second molar teeth that leave the lower second molars partially unopposed can also allow the distal aspects of these teeth to subsequently over-erupt and tip. 6 Indeed, while the potential for completely unopposed adult teeth to over-erupt by up to 5.4 mm with an incidence of 82-92% in such circumstances is well documented, 7,8,9 similar findings have also been demonstrated for teeth that are partially unopposed, albeit with comparatively greater degrees of tipping. 10 As a consequence, just over a half of all types of over-erupted teeth are involved with either retruded contact position and/ or excursive interferences.…”

that her general dental practitioner had supplied, primarily as a means of managing her temporo-mandibular joint (TMJ) dysfunction and secondarily as a long term orthodontic retainer. However, the lower second permanent molars had never been completely incorporated within the BRA splint (Fig. 1).As a result, the distal aspects of these teeth had over-erupted and through the consequential downwards and backwards rotation of the mandible she had developed both an open bite and an increased overjet (Fig. 2). Yet evidence that she had previously had an anterior occlusion could be seen by the presence of occlusal wear facets on her upper incisors and canines.In this regard she had been referred for treatment to improve her TMJ dysfunction through the correction of her open bite. She was therefore supplied with an upper removable appliance with bilateral posterior bite blocks that were positioned over the upper third molars. These made selective, solitary contact with the distal cusps of the lower second molars whenever she occluded her teeth. Elsewhere, occlusal stops were placed on the remaining upper premolar and molar teeth in order to prevent them from over-erupting during the process of closing the bite (Fig. 3). After six months of maximum part-time wear her lower second molars had been sufficiently intruded to regain her original occlusion (Fig. 4). Although this resulted in an improvement of her TMJ symptoms,

“…La secuencia del síndrome de colapso de mordida posterior se inicia por la pérdida dental. Generalmente es el primer molar inferior por las características asociadas (erupción temprana en boca y susceptibilidad a la caries por dificultades en la higiene oral en las primeras etapas de la vida) 65 . Posteriormente se generan malposiciones dentales, tipo extrusiones, versiones y rotaciones, entre otras, que generan interferencias en los movimientos funcionales, produciendo alteraciones en la estructura dental, periodontal, muscular (posicionamiento anterior) y abanicamiento de dientes anteriores superiores 66 .…”

Resumen: Introducción: Muchos de los lineamientos sobre oclusión y de las alternativas de tratamiento en paciente dentado y parcialmente edéntulo, se basan en conceptos planteados en los inicios de la profesión. La diversidad de escuelas de oclusión ha hecho que, algunos de esos conceptos se tornen complejos para su entendimiento y aplicación. Esta diversidad hace que la compresión de la fisiología oclusal y sus alteraciones sea difícil, obstaculizando el entendimiento de la patología oclusal, su correcto diagnóstico y manejo. Objetivo: Es por esto que se realizó una revisión bibliográfica sobre fisiología y patología oclusal, con el propósito de recopilar información basada en la evidencia científica, que permitiera esclarecer conceptos y homogenizar el conocimiento a cerca de los cambios en la fisiología y morfología del sistema estomatognático, asociados a las alteraciones oclusales, permitiendo a futuro la estandarización del proceso de diagnóstico oclusal en la Facultad de Odontología de La Universidad Nacional de Colombia. Metodologia: Se realizó una búsqueda en bases de datos MedLine, PudMed, Ovid, Ebsco, ScienceDirect y Hinari-Healthinternetwork mediante los términos Mesh "Dental Occlusion"-"Stomatognathic System"-"Masticatory System" -Temporomandibular Joint y las palabras de texto libre pertinentes, así como las bibliografías de los trabajos y artículos de revisión que tuvieran relacion directa con el tema; no se tuvo en cuenta la fecha de publicación. Resultados: Se obtuvo un total de 79 artículos, 10 textos y 7 páginas web. Conclusión: la patología oclusal es un proceso evolutivo que puede afectar cualquiera de los componentes del sistema estomatognático en su forma y/o función. La armonía oclusal es un estado en el que cada una de las partes del sistema funciona coordinadamente para cumplir las funciones de masticación, fonación y deglución; la rehabilitación oral debe encaminarse hacia la obtención de una oclusión armónica. Palabras clave: Oclusion dental, Sistema Estomatognático, Oclusión dental traumática, Articulacion Temporomandibular.Evolution of occlusal pathology. A literature review.Abstract: Introduction: Many of the guidelines on occlusion and treatment alternatives in dentate and partially edentulous patients, are based on concepts raised in the beginning of dentistry. The diversity of the occlusion schools has become some of these concepts complex to understand and apply. This diversity makes difficult the compression of the occlusal physiology and its disorders, hindering the understanding of the occlusal pathology and its proper diagnosis and management. Objective: This is why we conducted a literature review about oclusal physiology and pathology, in order to gather information based on scientific evidence, which in order to clarify concepts and homogenize knowledge about physiological and morphological changes of the stomatognathic system, associated to occlusal alterations, allowing the future standardization of the occlusal diagnostic process at the Faculty of Dentistry of the Nat...
